Modern duplex stainless steels have been in use since the early 1970s and cast versions of the wrought alloys were soon in demand for pumps and valves. Since that time a range of cast duplex stainless steels have been developed with a wide range of compositions, but all with approximately 50/50 austenite/ferrite phase balance and deliberate ...

Duplex stainless steels like S8490 ("duplex") and SAF2507 ("super duplex") have excellent corrosion resistance combined with high strength, due to their fine grained two-phase structure. Martensitic stainless steels like S134M and S165M are tough even though they have been hardened to a high tensile strength of 800-1,000 MPa.

Duplex stainless steels are a family of stainless steels that are lean in nickel and provide several distinct advantages as a material of construction in addition to their price stability. Lean duplex stainless steels, such as LDX 2101 and AL 2003 are leaner in nickel and molybdenum content in comparison to the duplex 2205 and superduplex 2507.
